Please type answer, can't see written answerswell.
Also PLEASE PROVIDE BELL SHAPED CURVE** That isthe part I struggle with the most.
The airlines industry measures fuel efficiency by calculatinghow many miles one seat can travel, whether occupied or not, on onegallon of jet fuel. The following data show the fuel economy, inmiles per seat for 17 randomly selected flights on Delta andUnited. Assume the two population variances for fuel efficiency forthe two airline are equal.
Delta
| 65.80 |
| 81.40 |
| 58.90 |
| 73.60 |
| 53.20 |
| 49.80 |
| 68.30 |
| 61.40 |
| 73.10 |
| 67.60 |
| 72.20 |
| 61.00 |
| 52.70 |
| 71.40 |
| 44.90 |
| 55.90 |
| 86.70 |
United
| 82.10 |
| 58.80 |
| 60.00 |
| 57.90 |
| 45.20 |
| 54.30 |

a. Conduct a the 95% confidence interval estimate of thepopulation?
b. Perform a hypothesis test using ? = .05 to determineif the average fuel efficiency differs between the twoairlines.
c. Determine the p-value and interpret theresults.
